ATTINY44A-MU Description

Short technical summary and product information.

The ATTINY44A-MU is a low-power, high-performance 8-bit AVR microcontroller from Microchip Technology. It integrates 4KB of in-system self-programmable Flash memory, 256B of SRAM, and 256B of EEPROM with high endurance (100,000 write/erase cycles for EEPROM). The device operates at a maximum clock frequency of 20 MHz and supports a wide supply voltage range from 1.8V to 5.5V, making it suitable for battery-operated and low-voltage applications.

 

Key peripherals include a 10-bit ADC with 8 single-ended channels and 12 differential channels, two PWM-capable timers, an analog comparator, a temperature sensor, and a watchdog timer. The microcontroller also features Brown-out detection, Power-on Reset, and an internal calibrated oscillator. Connectivity is provided via a Universal Serial Interface (USI).

 

The ATTINY44A-MU is offered in a compact 20-pin WFQFN exposed pad package (20-QFN-EP, 4x4mm), supporting surface-mount assembly. The operating temperature range is -40°C to 85°C, suitable for industrial environments. With its rich set of peripherals and low-power modes, it is designed for embedded control applications such as sensor interfaces, data logging, and IoT devices.
